Description

[Detailed description of the invention] This invention relates to a carbonator that creates carbonated water by sprinkling water into a sealed tank pressurized with carbon dioxide gas, and has a simple structure that can increase the contact area between carbon dioxide gas and carbonated water. This aims to increase the production rate and the carbon dioxide concentration in carbonated water.

Examples of the present invention will be described below.

FIG. 1 shows an embodiment of the present invention in longitudinal section.

1 is a carbonator, and inside the cylindrical sealed tank 2 is an air supply pipe 3
Pressurized with carbon dioxide gas at a predetermined pressure introduced through the
Pressurized water is sprayed from the water supply pipe 4 by a water tap 5.

A float switch 6 controls the operation of the pump so that carbonated water is stored in the tank 2 within a predetermined range H-L.

The present invention is characterized in that the gas cup 7 to which the air supply pipe 3 is connected is disposed at a position lower than the level L in the tank 2.

Reference numeral 8 denotes a carbonated water take-out pipe that penetrates through the force scallop 7 and opens at the bottom of the tank 2.

The gas cup 7 is fixed to at least one of the air supply pipe 3 and the take-out pipe 8, and is structured to prevent gas from leaking upward from the joint between the air supply pipe 3 and the take-out pipe 8.

When the gas cup 7 is added in this way and carbon dioxide gas is introduced into the gas cup 7, the inside of the gas cup 7 acts as a gas reservoir and becomes filled with carbon dioxide gas under the water level shown in the figure. As a result, a carbon dioxide layer is formed, and the opening surface of the gas cup 7 and the carbonated water 9 come into contact with each other over a wide area, promoting dissolution of the carbon dioxide gas.

Since the carbonated water 9 near this contact surface is taken out, high quality carbonated water can be provided.

Further, the carbon dioxide gas overflowing from the gas cup 7 becomes a bubble and rises from the opening edge of the gas cup 7, thereby promoting the dissolution of the carbon dioxide gas.

Therefore, in this carbonator 1, contact occurs when water droplets from the water tap 5 fall into the carbon dioxide gas, contact occurs between the water surface of the carbonated water 9 and the opening surface of the gas cup 7, and carbon dioxide gas contacts the opening edge of the gas cup 7. Highly concentrated carbonated water is produced at a high production rate due to contact as it overflows from the carbonated water and rises in the carbonated water 9.

Such a carbonator is used, for example, in a type of vending machine that mixes syrup, cola, etc. and carbonated water at the time of sale, among vending machines that measure and sell carbonated soft drinks into cups.

FIG. 2 shows another embodiment of the present invention, in which the gas cup is arranged in two stages in the vertical direction.

In particular, the air supply pipe 3 is connected to the lower gas cup 10 by passing through the upper gas cup 7, and carbon dioxide gas is transferred to the upper gas cup 7 through a connection with a slightly shallower length than this to the upper end surface of the lower gas cup 10. A lower gas cup 10 is installed with a pipe 11 inside.
When the inside is filled with carbon dioxide gas, the carbon dioxide gas rises through this communication pipe 11.

The length of the communication pipe 11 for this purpose should be shorter than the depth of the gas cup 10 so that there is a difference a between it and the lower end of the lower gas cup 10.

In this way, the contact area between carbon dioxide gas and carbonated water 9 becomes even larger, so that the production rate of carbonated water and the dissolved concentration of carbon dioxide gas can be further increased.

The method of introducing carbon dioxide gas into each gas cup in this embodiment is, for example, by branching the air supply pipe 3 into two in the middle, or by making the diameter of the lower gas cup smaller than that of the upper gas cup. Carbon dioxide gas can be introduced into each gas cup without using the communication pipe 11.

Of course, such gas cups may be provided in two or more stages.

As described above, according to the present invention, high-quality carbonated water can be obtained by promoting the carbonation effect with a simple structure.
